Answer:
7.5 Hours
Step-by-step explanation:
(18 pages per hour) * (x hours) = (135 pages)
18x pages = 135 pages
18x = 135
Divide both sides by 18 to get rid of the 18 and to get x on its own.
x = 135 / 18
x = 7.5
Mary would take 7.5 hours to complete the book.
Answer:
It will take about 7.3 years for his money to triple.
Step-by-step explanation:
Identify the variables in the formula.
A = 150,000
P = 50,000
r = 0.15
t = ?
A = Pe^rt
Substitute the values into the formula.
150,000 = 50,000e^0.15*t
Solve for t. Divide each side by 50,000.
3 = e^0.15*t
Take the natural log of each side.
ln 3 = ln e^0.15*t
Use the power property and then simplify.
ln 3 = 0.15*t ln e
ln 3 = 0.15-t
Divide each side by 0.15.
(ln 3)
/(0.15) = t
Approximate the answer.
t ≈ 7.3
Answer:
The probability that the box will contain less than the advertised weight of 453 g is 0.00034.
Step-by-step explanation:
Let <em>X</em> represent the weight (in grams) of cereal in a box of Lucky Charms.
It is provided that <em>X</em> follows a Normal distribution with parameters, <em>μ</em> = 470 and <em>σ</em> = 5.
Compute the probability that the box will contain less than the advertised weight of 453 g as follows:
*Use the <em>z</em>-table.
Thus, the probability that the box will contain less than the advertised weight of 453 g is 0.00034.
Total number of cakes made by Simon = 30 cakes.
Number of cakes gave to Sali = 1/5 Of total cakes = 1/5 * 30 = 6 cakes.
Number of the cakes gave to Jane = 10% of 30 cakes
10% can be written as 10/100 in fracions and in decimals it would be 0.10.
Therefore, 10% of 30 cakes = 0.10 times 30 = 3 cakes.
Total number of cakes left = Total cakes made - Cakes gave to Sali - Cakes gave to Jane = 30-6-3
Therefore, Total number of cakes left = 21.
21 cakes left our of 30 cakes.
21 out of 30 could be written in fracion form as 21/30.
We can reduce this fracion in simplest form by dividing top and bottom by 3, we get
7/10.
Therefore, 7/10 fraction of the cakes does he have left.
